Hey there! :)

Answer:

75.4 cm.

Step-by-step explanation:

Formula for the circumference of a circle:

C = 2rπ

Given:

r = 12 cm

Plug this value of r into the equation:

C = 2(12)π

C = 24π

Multiply by π (3.14)

24 × 3.14 = 75.36 cm

Round to nearest tenth:

75.36 ≈ 75.4 cm.

Answer: B

Step-by Step: C=2n

r= 2•n•12= 75.39822

You round it to the nearest tenth, it would be 75.4
